v V the illustrated embodiment, the invention is shown applied to andcooperating wvith a machine substantially similar to that appliedthereto inv the patent appended in parentheses after the referencenumeral ap plied thereto in the present application.

The shape a: (m) is impelled forward against a head 1 (2 6); mounted'ona carriage 2 (),.which carriage slides along a guide way 3 (15)extending the path of travel of the work 00''. Likewise extending alongthe path of travel of the work is the screw shaft 4 and the latch 5(46), which is operated and controlled by the solenoid 6i and is adaptedatthe proper time, in accordance with the desired travel or distance offeed of the work, to engage with the screw shaft 4 (40) the two movingin engagement and cooperation to complete the desired or measured travelof the work. The energized foot,'or other unit, bar 7 acts to energizethe solenoid and the trolley wires 8 (64) (116) (13 4) complete ,orreturn the various circuits.

The shaft 10 is a continuation of shaft (iO), and they are rotatedthrough a friction clutch ll (76) and shear train r12, 13 (78, '79) froma motor 14:

The distance determining device, indibated generally by 1,5, 16 (89, 86)is connected to shafts 1M0) and 10 (7 5) through a gear 17 (82) and apinion .18 (81). The

sleeved on shaft 10 and is integral with or fined to a clutch member 22likewise sleeved on the shaft. A cooperating clutch member 23 is mountedto rotate with the shaft 10 In the present embodiment, pinion 18 is Ibut is slidable therealong to engage and disengage 22, in a well-knownmanner. The operation of clutch 22, 23 is effected and controlled by amechanism indicated generally by reference numeral 2%," which mechanismis shown and described in the application I of "George.

inches and sixteenths thereof over an" inte 'gral foot rcqulred 1n theparticularmeasurcment or travel'of the work which is being made. i LSaid means as embodied comprises cooperating devices whereby the screwshaft is returned to zero when a distance reading or setting extendsbeyond thenext lntegralioot from the last prev ous reading; and, whenthe next distance reading or setting is be yondthene xt inch: but isin'wthe same integral foot, for permitt ng the inch-.plns and .thesixteenths-otan-lnch slotted disk to return. to ZGIO under the impulsionof the gravity, or other automatic pressure device;

and also, when the next succeeding distance sett ng or readlng '1s 1nthesame 1nch,'for

preventing the restoration 7 of the inch disk t0 the Zero 7 V The term"Zero, herein is merely con- ..ve11iently employed for any initial orbasic point, and'thej term restoring is conveniently' employed;forbringing the rotating disks or equivalent distance determining devicesinto basic or standard relationship therewith.

The deta'ilsof construction and operation of the inch and iractlons ofan infill part of ti e distance determining mechanism are clearly. setiorth'in said Hawthorne Patent No. 1,241,258, and need not be .repeatedherein. It may be stated briefly that the plate 30 (S9), mountedj-infixed position on the machine frame, carries the solenoid operated'pins31 (101) which are'automatically settablefor the sixteenths-of-an-inchin the desired, distance reading; 1 The rotatable disk 32 (88),.has theslots 331(100) therein,

which 7 are positioned when the corresponding pin is set, to give anydesired feedup to fifteen-siXteenths-of; an-i'nch.

The'disk32 (88) fix ed thereto a sleeve 34: (87), 1nounted on shaft 35Fixed to sleeve 34 is a disk 36 (86). in which arevmounted the solenoidoperated inch pins :37

(9.1). Cooperating with pins 37 (91 is the gear wheel 1 (82) which ismeshed with 1 pinion 18 (81), the distance determining 'deif as vicebeing thus connected'to control the rota tionof shaft 4 (40) to effectthe desiredfeed or travel of the work 00, the disks traveling andproportioned,

proportionatelyto the work, under the (.011- trol of the -distance"determining device which in the present, embodiment controls 7 thesetting of the inch pins and the size teenths pins. v

In the side of gear wheel 17 which faces disk 36 (8.6) with its pins 37(91) in a slot 39 0), into which slot a selected pin 37 g (91) isautomatically set or projected by-a suitable distance'record device, theso set pin engaging the end of the slot to stop the gear wheell'fafterthe desired distance of travel of the work, the disk 36 and get;

wheel 17 then traveling together so far as permitted bythe'setsixteenths? pin 31, to glve or permit the desired or set distanceof travel of the work beyond the lastintegral inch of the distance. i 1

Beferring now more particularly to Fig.- 4, which is a flatidevelopnicnton anar-cuate sect'ion'through the center of the slot in Fig. .3 withthe pins shown in" full, the gear wheel 17 betweenthe ends o'f'slot' 39;forms an abutment or stop "for the inch pins 87.

In the bottom er the slot 39 there'are holes 4-0 spaced one inch apartof smaller size or diameter than the pins 37.

Qneof the pins 8(,

a. projection 41 adapted to enter any onset the holes 40' which may 'be'in registerthere- 'with. Uneof these. holes will always bein registertherewith at any inch se ting, as the pins 37 are. an inch apart and theholes 40 are also an inch apart r h p I Theprojection ii is preferablyconical in form, the holes 40 being correspondingly shaped, to permiteasy release of the pin from the hole.

v The inch pin carrying the projectitnr i' is connected incircult sothatwhen the pin y, which is any oneof the M1011 pins, strikes -the end ofslot 39, as shown; in Fig. 4, and

1t 1s desired. to holdthe disk 36. onthe same. inch, inch-pin w 1s proected, into hole o of hole '0; Pin a is then de'energizednndreitracted,-and gear 17 and disk '36together. will rotate for thefraction of an inch called for bythe new setting of the sixteenths-oir}an-1nch pm which has been made in the new inch. The pin '20 of the.inchpins' may be 7 r the one which holds 'disk;36 atan. initial or zeroposition andis thus adapted to carry the projection, 41' withoutotherwise inter fering with the operation ofthe mechanism. In accordancewith one feature of the present invention, means are provided foreffecting a. feed of the .work :20 for. a subthe general mechanism;'Asembodiedithis for instance the "eleven-inch pin, is provided its endwith multiple of the ultimate fractional feed of is a feed for athirty-second of .an inch, which is half the distance between twoadjacent settings of thedisk.

AS. embodied, the plate. so, is notfa fixed carrier or bearing for thesiXteenths-of-an- .inch pins, but the part 45-thereof (Figs. 6

and 7) is circular in formand is carried within a ring 46, which ring isfixed relatively to and carried upon the frame 47 of the machine. Thisdisk 45- carries the size 7 ring 46.

Mounted on ring46 is a solenoid 48, the core. 49 thereof having a pin50-.attached thereto. The pin 50 works in an aperture 51 in the ring 46and is impelled by its spring 58 to project into a recess 52 in the disk45. This holds disk fixed in ring 46 during measurements terminating. inan even inch or insiXteenths-of-an-inch.

1 In the periphery of disk 45 is a second aperture 54,11aving adimension in the periphery of disk 45 permitting a thirty-second ofan'inch of feed of the work 00. Into the aperture 54 projects a pin 55fixed in the ring 46. When solenoid48 is energized, it retracts pin anddisk 45 is permitted to rotate'the equivalent-of a thirty-second of aninch of: travel ofthe WOl'k- Thustwhenever it isdesired to addathirty-second to any distance reading or distanee' of travel "of thework, the solenoid 48 is energized.

preferably from the distancerecord device, and retracts pin 50 againstits spring and permits rotation of disk-45 until pin strikes theopposite side of aperture 54. The disk 45 is restored'by the automaticpressure device (shown in Fig. 7 as a spring 56), and the solenoid 48having been deenergized, pin 50 again enters'qaperture '52 undertheimpulsion of spring58. Wveight 57 acts to restore the entire diskmechanism to initial po'sition, the spring 60 in Fig. 4 corresponding tothe weight 57.

It will be understood that the references to the foot and inch system ofmeasurements,

and likewise to the sub-multiple or fractions,

sixteenths and thirty-seconds, is illustrative [merely and notrestrictive of the invention.

V In the embodied form ofcontjrol by a distance record device, that is asheet or other device in which-has been punched or marked the positionrelatively to the beam of the 'holes to bepu'nchedand the distancesbetween them (Fig; 1), contact point's'til, 62

jand63 areenergi'zed from a source of electric energy 64, and makeelectrical contact,

- through perforations 65in a distance record sheet 66, with opposed.contacts 67; 68 and 69, which in turn connectdn circuit with contactorcoils 0, '71 The opposite ends of these coilsare'c'onnected to anegative line 73. The contactor coils .Wl'IGD'GIlergized serve to closetheir respective contactors, 74, 75. and 76. Contactor 74, when closedenergizes the solenoid coil whichsets the-stop pin 31 for the particularselected or desired sixteenth-of-an-inch of travel. Contactor likewiseacts to set stop pin 37 for the particular selected or desired inch oftravel. Contactor 76,, when closed, opens the circuit of the solenoidcoil of stop pin 50,

thereby releasing thispin and allowing the mechanism to advance throughthe desired additional thirty-second of an inch, if such a measurementor advance is required.

The invention in its broader aspects is not limited to the details ofconstruction'shown and described, but changes maybe made therefrom,without departing from the principles of the invention and withoutsacriiicing its chief advantages.
